Trigg Mining unveils ‘significant’ exploration target for Lake Throssell SOP project

Trigg Mining (ASX: TMG) has unveiled a “significant” exploration target for its Lake Throssell sulphate of potash project in Western Australia, which it claims highlights the asset’s large-scale potential and high-grade SOP.

The exploration target covers about 70km of strike out of a total length of 112km. It is based on 36km of exploration results from the palaeovalley, plus a further 34km of strike which is considered to have similar geology and brine characteristics.

All up, the initial exploration target assumes 7.5-27 million tonnes at 9,000-10,000 milligrams per litre of SOP equivalent.

Trigg managing director Keren Paterson said the exploration target was a “very significant” first step in evaluating the “enormous opportunity” Lake Throssell represents.

“These early results are very encouraging and support our believe in the potential of Lake Throssell to host a sustainable long-life, low-cost source of primary SOP for global food security.”

Aircore drilling underpins upcoming resource

An aircore drilling program kicked-off at Lake Throssell in late November last year and is focused on the palaeovalley sequence within the project that was identified from an earlier gravity survey.

Prior to the end of December, 16 holes were completed for 1,806m. Analysis from preliminary holes has shown a similar composition and grade to the surficial sediment body. The average brine grade to date is 9,780mg/L SOP equivalent.

Prior to Christmas, Trigg had submitted 74 brine samples for analysis. Of these, 93% of the assays had exceeded 9,000mg/L SOP, with 32% of samples having grades higher than 10,000mg/L SOP.

Due to the positive results from the current aircore program, Ms Paterson said the company has increased it to comprise 50 holes.

“The program is on track for completion by the end of February, weather permitting, and we anticipate receiving the assay results approximately four weeks later,” she noted.

“These results will then pave the way for our maiden inferred mineral resource estimate for Lake Throssell – the company’s second mineral resource estimate since listing,” she added.
